Avoid using bash special device nodes.

Bash has special handling when these standard IO files, but
there are cases where customers have special restrictions set
on them. Likely to avoid leaking error data out of system logs
as part of IDS software.

In any case, we can just reopen existing file descriptors here
in both these cases to avoid this entirely. This will always
work.
